Cold should not be used in a bacterial such an inflammation it is desirable that quantities of active leukoc}-tesshould come to the part. These phagoc}-tes destroy bacteria and circumscribethe inflammatory- focus. Cold keeps much blood and hence many leukoQ-tesout of the the ameboid activity, and prevents migration of theleukoc\-te5 which do succeed in arriving. Hence, cold actuaUy favors thespread of a microbic process. Fiirthermore, it lessens leukocytosis and thuslessens the protective reaction of the tissues. De Xancrede, in his Trinciplesof Surg
